NACT-024 [Uncensored Leaked] My First Woman is My Father's Mistress, Hibiki Otsuki

My parents divorced when I was little. I went to university and was living with my father, but I had a source of worry: my father's mistress, Hibiki. One day, Hibiki, who works at the cabaret club my father runs, asks me to take some photos to use in promotional materials. As the photos are being taken, Hibiki gets excited and kisses me, and although I have no experience, I accept instruction.
